WILLIAM K. HERBERT, OF MOKEESPORT, PENNSYLVANIA.

GARBAGE-GREMATORY.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed April 5, 1909. Serial No. 488,100.

To all whom it may concern:

Be it known that 1, WILLIAM K. HERBERT, a citizen of the United States, and a resident of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved GarbageCrematory, of which the following is a full, clear, and exact description.

This invention relates to a crematory to be used to destroy garbage and other refuse.

The invention consists broadly in a storing and drying chamber, an incinerating chamber, an auxiliary combustion chamber, and means to deodorize and cleanse the combustion gases.

The invention further consists in the construction and combination of parts, to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation of the device; Fig. 2 is a vertical longitudinal section thereof; Fig. 3 is a horizontal section on the line 3-3 in Fig. 2 above the grate of the incinerating chamber; Fig. 1 is a horizontal section on the line 4t in Fig. 2, below the grate of the incinerating chamber; Fig. 5 is a vertical cross section on the line 55'in Fig. 2; and Fig. 6 is a vertical cross section on the line 66 in Fig. 2.

Referring more particularly to the separate parts of the device, 1 indicates a combustion furnace in which the garbage is to be incinerated. It consists in a structure able heat by auxiliary fire boxes 9 and 10. Spaced apart from the foundation of the furnace, and supported by any suitable means such as walls 11, 12 and 13, is a grate 14:, on which the garbage to be incinerated is adapted to be placed. The grate 14 may be of any suitable material and form, but is preferably composed of longitudinal supporting members 15 and cross bars 16, spaced apart at intervals. Access is gained to the fire box 8by means of a door 17 and the ashes from this firebox 8 may be raked out through the opening which is closed by a door 18. In order to clean the top of the grate 14: of garbage or incinerated matter accumulated thereon there are provided doors 19 in the side of the furnace. There are also provided doors 20 at the bottom of the side of the furnace, to remove the particles of incinerated matter and the ashes which have fallen through the grate 14. The auxiliary fire boxes 9 and 10 are attended to through fire doors 21 and ash-pit doors 22.

In order to feed the matter to be incinerated to the incinerating chamber, there is provided at the top of the furnace a suitable casing 23, which is made of any suitable material and in any suitable form, but is preferably a cylindrical sheet metal container. There are openings in the upper side of the furnace 1, as at 24, corresponding with which are openings in the casing 23. In order to close these openings, there are provided on the casing 23 suitable doors 25, which are preferably curved, conforming to the surface of the casing 23 and adapted to slide between the openings in the casing and the openings in the top of the furnace. In the top of the casing 23 there are provided openings, which are closed by doors 26, which may be of any form and material, but are preferably curved sliding doors, similar to the doors 25. These latter openings are for the purpose of permitting the garbage and other material being inserted in the cats ing 23, which is for the purpose of drying the garbage before it passes to the incinerating chamber. On the side of the incinerating chamber atwhich the garbage falls through the openings 24:, there are provided slanting grate bars 27, which are for the purpose of keeping the material to be incinerated away from the side walls of the chamber, and thus permit the flames to circulate back of the material being incinerated.

There is provided in the top of the furnace 1 another opening 28, in which large articles to be incinerated, such as the carcasses of animals, may be inserted. This opening is closed by a suitable cover-plate 29, which may be connected in any suitable manner, as by means of a chain 30, to'a partially decomposed matter.

suitable hoisting device, such as a hydraulic' crane. In the end away from the fire box 8 in the incinerating chamber, there is provided in the wall 12, a plurality of openings 31, which form a checkered surface for the highly heatedgases' to, pass through. This checkered surface is heated by the fireboxes 8, 9 and 10, and also by the material being burned in the incinerating chamber.- This 331 into the out-take of a stack 34, which forms part of the furnacevproper, Th-e opening of the stack is preferably down near the b'ase of the furnace, as at 35, andis closed and opened'by means of adamper 36,

. .which may be' regulated ,by 'aconnecting.

rope 37 which passes over a suitable pulley support 88to a counter-weight 39.

f Situated near the base of the stack 34 is a suitable spray pipe 40, which is adapted'to spray hot water on the gases passing into the stack; This hot water is heated up to such a point that it partially. decomposes and unites with the productsof combustion, and also washes down the cinders and solid matter in thegases, at the same time taking out any'putrid odors. The bottom of the stack may be'connected inany'suitable matu ter to a drain, where any excess water will be carried ofito the sewer.

whichis used in the spraypipe 40 may be The water heated by means of a suitable coil 41, which is placed above the checkered surface j formed by the openings 31,: and through i .which a portion of the hot gases pass.

The water heated in this coil passes to a suitable hot water container 42. The water, may be circulated from the hot water container back i into the coil 41 by means of pipes 43 and 44, which are a'continuation of each other, and

a pipe 45. The water in this container 42' may be also usedto wash the garbage cans after they have been emptied, and an outlet j ofjany suitable kind, indicated at 46, is proyided for this purpose. 7 There is provided a suitableconnecti'on 47 between the drying casing 23' and the stack 84, to carry oif the moisture driven from the garbage. In the operationof the device, the fun.

i nace is first heated-by means of the fire, box

8 the ineineratingchamber gotten up to a goodv high temperature, and then the garbage to be incinerated" is "inserted through thewdo'ors-2 6 in the top of the casing 23, the

thefmeantime being closed, to

prevent any esea e" of gases into the outside air; When a' su cient; quantity or material has been placed in the casin 23, the top doorsi26 areclosed, and 'the' ottom doors 25 opened. The material in the casing 23 then commences to dry and shrivel up, the -moisture passing off through the pipe 47 into the stack 34, and the dried.fparticles falling downthrough the openings 24 to the grate of the incinerating chamber. Here the garbage is exposed to the fierce heat generated by the'fire boxes 8, 9 and, 10, and in burning up, it also adds to the temperature of the chamber.

If it is desired to insert large articles of refuse, such as the carcasses ofanimals,'they may be' inserted directly into the incinerating chamber through the auxiliary opening 28. When the incinerating chamber has once been heated up to a sufiicient temperature, the fire in the fire box S'maybe drawn, and the crematorywill be self-sustaining. However, it is generally advisable to keep small fires going in the fire boxes 9 and 10, to keep the under side of the grate l4 warm. The products of combustion in the incinerating chamber pass through the opening 31 in thecheckered surface, with the exception of a small portion which passes through the coil 41 in the water-heater, into the auxiliary combustion chamber 32, where the gases are further mixed after being heated up by the checkered surface, from whence they pass down to the base ofthe stack 84, where they are sub'ected' to the cleansing action of the spray of hot water.- The hot Water is partially broken up and unites with -the products of combustion and also washes the gases free from solid matter, at thesame time taking out the putrid odors. Thehexhaust wash water passes off into the drain, and thus into the sewer. I provide suitable openings, closed by the doors 48 and 49,- for the combustion chamber, to permit access to the same. v
